Abstract

L'invention concerne un copieur électrophotographique à source lumineuse fixe. Le faisceau aligné venant de la source 6 du copieur 4 est dirigé sur un organe balayeur 12 possédant des réflecteurs supérieur 20 et inférieur 14 d'éclairement de document constitues d'éléments minces de masse négligeable maintenus sous tension élastique. Le réflecteur inférieur 14 est formé de plusieurs plaques 16, 18 sensiblement horizontales disposées suivant un ensemble sensiblement vertical. La chaleur de la source lumineuse fixe est utilisée par l'intermédiaire d'une source froide 57 pour sécher ou fixer les exemplaires reproduits 48. La structure particulièrement légère des réflecteurs mobiles permet d'accroître la vitesse de travail du copieur.
